Run Coordinator Duties
- Give daily SLD report at 8:00 AM SLC meeting
(MCC) and at 8:30 AM SLD meeting (CEH).
- Talk to SLC program deputy and make program
decisions.
- Write daily run status report and record daily
telephone message.
- Keep white board problem and message lists
up-to-date, check action item list, follow up on
problems.
- Keep track of luminosity and background noise
trends. (See logging guide for discussion of good
and bad beam conditions.)
- Review off-line shift reports, follow up on
problems.
- Oversee shifts and enforce shift discipline.
Check current and upcoming shifts, make sure
shiftees are available and prepared. Make sure
shiftees do checklists, spews, calibrations. Help
train shiftees (especially experts) who have
insufficient experience.
Run Coordinator's Daily Report
- The normal daily report should include a brief
shift summary for the last three shifts,
including people on shift, running conditions,
and problems. SLC and SLD online Z counts should
be reported. The set of standard background plots
and the polarization plot should also be shown.
The Monday morning report should include a
summary of the week's running with off-line Z
counts. Copies of all or these reports should be
pasted into the Run Coordinator logbook for
future reference. There are two possible methods
for creating these reports.
Writing the report using Netscape
GOLD
- Make sure you are using Netscape GOLD
(you can tell by the presence of
an edit button on the
toolbar). You can start Netscape
GOLd on the CEH MAC from the
desktop icon.
- Either
- Open a previous report
using File...Open
File in Editor. The daily
reports can be found in
"Desktop...Run Coordinator
Files...HTML Status
Reports"
- or
- Use the Report Wizard to
create a new document.
- Press the Edit button in
the toolbar to begin
editing
- Save the new report in
the directory mentioned
above.
- Print the report using the print
button, and save it for future
reference.
Writing the report using WORD
The report should be written and filed
on the MAC in the CEH (next to the
printer). The simplest method is to
select a recent report, edit the
contents, and file and print the new
report. MAC and WORD novices can try the
following prescription:
- Open file with previous report:
double click SLD Run Coordinator,
double click Status Reports File,
double click < file with
previous report >.
- Edit old report to produce new
report: click and drag cursor
over old text to be deleted
(selection turns blue) type in
new replacement text.
- File new report: click File on
top menu bar (next to Apple),
drag cursor to Save as ...
option, enter new file name with
appropriate date, click Save (or
just Return).
- Print new report: click File on
top menu bar (next to colored
Apple icon), drag cursor to Print
Shift Summary
The daily shift summary should be based on the
shift reports written by the expert at the end of
each shift. These summaries are pasted into the
SLD logbook and entered into the Oracle database.
To access the reports from an SLD SCP running on
SLDACQ:
- Navigate to the Shifts panel (Index
-> Oracle Database -> Shifts)
- List the desired report (List + Shift
Report + < select shift >
+ Execute).
Online Z counts
SLC luminosity measurements are used to make a
running online estimate of the number of Zs
produced by SLC and recorded by SLD.
From the MCC SCP (left end of Star Wars
console):
- Navigate Index -> Special
Display -> Lum History Plots,
- Select the desired quantity to plot:
- SLC INTZ * BSM (SLC Z count)
- SLD INTZ * BSM (SLC Z count,
gated by SLD livetime)
- SLD CDC ON * BSM (SLC Z count,
gated by CDC voltage)
- Select last 24 hours or set explicit
begin and end times (to set the begin and
end times: Plot Scale Panel -> Enter
X Scale), record the numbers ... get
the difference max - min
- Select Print Graph Display to get a
printout. (optional)
Off-line Z counts
Off-line Z counts are best accessed using the
SLD status display. The Z count for the last few
days, calculated from the online Bhabhas and
summed by shift is available on Page 18. The Z
count for the last 24 hours is also available on
this page. The page updates every 30 minutes,
so the best time to get the 24 hour summary for
the 8am MCC meeting is just after 7:30am.
The count of the off-line Z's for the run to
date is available on Page
14. Use only the CDC on number so as not to
confuse people at MCC. This number is updated as
off-line processing of the data is completed, so
it can lack behind the data taking by a few hours
or more.
Background Plots
From the MCC SCP (left end of Star Wars
console), navigate Index -> IP
Status -> SLD 24hr macro. This will
automatically print three standard noise plots on
the IMCEH0 printer. Individual history plots for
the different noise signals are available in the
SLD History Panel. The DC noise plot showing the
average noise and tails is particularly useful.
Polarization Plot
From the SLD POLSCP (across from MCC SCP),
navigate Index -> Compton Polarim
-> Data Quality -> ABS(POL) CKV
(fxdscale). This generates a nice
polarization plot with error bars.
Run Status Report
The daily run status report is a computer message
distributed to the world at large through SLD news. It
should summarize the past 24 hour's running, including an
update on SLC performance and problems, any SLD hardware
or software problems, plans for the current day, and a
luminosity summary. A printed copy should be pasted into
the Run Coordinator log book.
A simple web based wizard is now available for
creating these daily reports.
Run Status Telephone Message
The daily run status telephone message is a recording
available to the world at large by dialing (415)
926-2011. To record a new message, dial 5110 and follow
the prompts:
- enter mailbox: 1000#
- enter password: 1000#
- enter 5 to record new message (terminate with #)
- enter 2 to review recorded message (terminate
with #)
Off-line Shift Reports
The run coordinator should be informed if the people
checking the SLD off-line processing discover any serious
anomalies. It is also possible to use the web based
interface to check on the off-line data and processing.
Beware, the web interface tends to omit data from sums
and tables when any portion of the data is unavailable.
This can lead to bizarre and misleading results.
Handy Phone Listings
Should be available on the center portion of the Star
Wars Console. In addition, the SLAC Phone Directory on
the WWW has a handy search form.
